Dealing with constantly changing privacy rules and more informed users makes gathering and using data for web analytics quite a challenging task. Google Analytics 4 (GA4) offers a solution in the form of consent mode. This feature allows you to manage data collection and usage in accordance with user consent preferences. By communicating these preferences directly to Google, you ensure compliance with privacy regulations like GDPR and CCPA while building trust with your audience. This new feature adjusts how GA4 works depending on whether users give permission for their data to be collected. It makes sure data is only collected when users agree, and it uses smart methods (Behavior Modelling) to still get useful information for those who choose not to share their data. This way, it helps gather the most valuable insights while being respectful of user privacy preferences.
In this blog post we will share with you how it works, what benefits can we get implementing it, what are the limitations and also answer some of the most common questions about this feature. We aim to help you understand this feature so you’ll have the confidence to utilize it. So let’s get started!

Plain and simple - let’s explain how it works
You want to use GA4 to track how visitors interact with your site, but you also want to respect their privacy choices. Here's how consent mode comes in:
Scenario:
- A visitor lands on your homepage. A consent banner pops up, asking them if they agree to cookies for analytics and advertising.
- The visitor chooses "Accept All." Consent mode transmits this choice to Google.
- GA4 tracks the visitor's activity normally, recording page views, clicks, and conversions. You get complete insights into their journey.
- Now, another visitor arrives and opts for "Deny All." Consent mode informs Google of this preference.
- GA4 stops storing cookies for this visitor. However, it can still gather some data using cookieless pings, like the page they landed on and the general time of their visit.
To fill in the missing information, GA4 uses behavioral modeling. This analyzes the behavior of similar users who did consent, and applies those patterns to estimate the non-consenting visitor's actions.
In short, consent mode helps you analyze the data collection in a “privacy-conscious” way, but also makes sure you get valuable insights while respecting user privacy and preferences.
Breaking down the benefits of GA4 Consent Mode:
Let us share with you these top 3 benefits of why you need to implement GA4 Consent mode in your website.
1. Consent mode enables alignment with privacy regulations like GDPR and CCPA. By capturing and respecting user consent preferences, you reduce the risk of legal repercussions associated with data collection.
2. Respecting user consent choices encourages trust and promotes transparency in your data practices. This can positively impact brand perception and engagement, and will eventually lead to potential benefits like increased customer loyalty and even advocacy.
3. By excluding data from non-consenting users, consent mode helps to eliminate bias and misrepresentation within your analytics. This results in more accurate and reliable insights into your actual audience and their behavior, and thus, enabling more informed decision-making.

Levels of GA4 Consent Mode
In GA4 Consent Mode, users can grant or deny consent for different types of data collection and processing. These consent levels offer granular control over what information Google can access and use for analytics and advertising purposes. It’s important that you understand these levels to help you decide on how to properly set up consent mode.
Let's explore each level in detail:
1) ad_storage:
This level controls the use of storage mechanisms (like cookies) specifically related to advertising.
Granted: If granted, Google can store data relevant to targeted advertising, including user interests and ad interactions.
Denied: Denying this level prevents Google from storing any advertising-related data about the user. They will no longer see personalized ads based on their browsing behavior.
2) analytics_storage:
This level governs the use of storage mechanisms for collecting and storing basic website/app usage data.
Granted: When granted, Google can store information like page views, session duration, and user engagement for website/app analytics.
Denied: If denied, Google cannot store any user data for analytics purposes. You will only see aggregated, non-identifiable data in your reports.
3) functionality_storage:
This level controls the use of storage mechanisms for essential website/app functionalities.
Granted: With consent, Google can store data needed for features like remembering language preferences, login information, or shopping cart contents.
Denied: Denying this level can severely impact website/app functionality. Features requiring stored data may not work or require constant re-authentication.
4) personalized_ads:
This level specifically controls whether Google can use collected data to personalize advertising shown to the user.
Granted: If granted, Google can utilize user data to show targeted ads based on their interests and online behavior.
Denied: Denying this level prevents Google from personalizing ads for the user. They will still see ads, but they might be less relevant to their interests.
5) security_needs:
This level covers the use of data for security purposes like fraud prevention and abuse detection.
Granted: With consent, Google can use data to identify and prevent fraudulent activity or security threats.
Denied: Denying this level might limit Google's ability to ensure platform security and protect users from fraudulent activity.Understanding these consent levels allows you to configure your website/app to respect user privacy preferences while still gathering meaningful data for analysis and targeted advertising. Remember, your choice of consent levels will impact the data available to you and the effectiveness of your advertising campaigns.
Implementation of GA4 Consent mode
You have the option to activate consent mode on your websites with minimal coding by utilizing Tag Manager and Consent Management Platforms (CMP). CMP Partners offer Tag Manager templates along with instructions for implementing consent mode through their integration.
The other approach is with the help of your web developers, you can integrate consent mode by enabling the gtag.js consent commands or a tag created from a Tag Manager consent mode template. Here’s a complete instruction for web and app.
What are GA4 Consent mode best practices
It’s enough that we only know how it works and how to make it work, so we like to share with you these best practices that can help you ensure transparency, compliance, and data quality:
Transparency and User Control:
- Be clear and transparent with your consent options. One way to do this is to explain what data is collected at each consent level and how it's used, giving users a clear understanding of the implications of their choices.
- Make sure that there is easy access to consent preferences. You can provide a readily accessible link or button for users to manage their consent choices anytime.
- It’s a must that you respect user choices. Honor user consent preferences consistently across all data collection and processing activities.
Technical Implementation:
- Set default consent state and determine appropriate default consent settings based on your audience and regional regulations.
- Load page tags before the consent dialog and make sure relevant tags are loaded even before the consent banner appears, avoiding data loss for initial page views.
- Load Google tags in all cases even if users deny consent, send cookieless pings to enable basic data collection and improve modeling accuracy.
- Integrate with a reliable CMP. This is very important - Choose a reputable consent management platform with robust features and seamless integration with GA4.
Data Management and Analysis:
- Maintain separate reporting for different consent levels: Analyze data separately for consented and non-consented users to understand the impact of consent choices on your metrics.
- Utilize modeling effectively: Leverage GA4's modeling capabilities to fill data gaps for non-consenting users, but be aware of potential limitations in accuracy.
- Prioritize privacy-friendly alternatives: Consider privacy-focused analytics tools or server-side data processing alongside GA4 for enhanced user privacy.
Compliance and Legal Considerations:
- Stay up-to-date on evolving regulations: Regularly review and adjust your practices to comply with the latest privacy regulations.
- Consult legal counsel: Ensure your website's data collection and use practices comply with applicable laws and regulations in your target regions.
- Maintain clear privacy policies: Update your privacy policy to reflect your use of GA4 Consent Mode and clearly explain how user data is collected, used, and protected.
Additional Tips:
- Test and refine your consent workflow: Conduct A/B testing to optimize your consent banner design and messaging for optimal conversion rates.
- Educate your team: Share best practices and guidelines for handling user consent and data privacy with your internal teams.
- Continuously monitor and optimize: Regularly review your GA4 Consent Mode performance, data quality, and user behavior to identify areas for improvement.
Limitations of GA4 Consent Mode
There’s no perfect tool as they said, so here are what we’ve gathered about the limitation of this feature:
- Consent Mode uses modeling to estimate behavior for non-consenting users, it's not perfect. This is because predictions can be inaccurate, and historical data can't be recovered.
- If the user did not consent, key features like Realtime reports, Explorations (except free-form), Audiences, Segments, Predictive Metrics, and Data Export are unavailable.
Technical Limitations:
- The setup could be complex since it requires adjustments to tags and configuration based on user consent levels.
- It’s incompatible with other platforms and technologies. Consent Mode only affects Google tags (GA4, Google Ads, Floodlight, etc.), not pixels or tags from other platforms like Meta or TikTok.
- Google controls the modeling algorithms, and you have limited access to customize or refine them.
